If Sing fumbles, I think that he will regroup. If Cook fumbles then it's a crapshoot. I know that I'm not giving the rook a chance, and I own that. Still, if you get a chance to do the little things in a game, I don't know, like catching a single pass, then do that. If you get a chance to have a carry, don't fumble. If you do those things then, as a rookie, on a comparably stacked team, you will get more chances.
